Title: Color electrophotographic copying machine
Inventor: KASAHARA NOBUO
IPC: G03G15/01
Filed: 1984-04-27
Abstract: PURPOSE:To eliminate a waste of electric power and to speed up copying operation by switching copy process speeds automatically associatively with mode switching. CONSTITUTION:Exposure is carried out in monochromatic copy made without a color separation filter 5, so the quantity of exposure of a photosensitive body is >=3 times as large as that in full-color mode as long as the exposure time is the same. Further, overexposure for color fogging suppression is not necessary, so the exposure time is much less than one third as long as that in full-color copy mode and the turning speed of the photosensitive drum 1 is increased to >=3 times as fast as that in full-color copy mode. For the purpose, the turning speed of the photosensitive drum, the conveying speed of transfer paper S, and the condition of a copy process are switched at the same time associatively with the selective switching of copy mode to take a full-color and a monochromatic copy without any trouble. Consequently, the turn-on time of an exposure lamp 3 in monochromatic body mode and, therefore, power consumption are reduced and the time required to take one copy in monochromatic copy mode is reduced to one tenth as long as that in full-color copy mode.

Title: Space diversity receiver
Inventor: YAMAMOTO KAZUHIRO
IPC: H04B7/26
Filed: 1982-05-21
Abstract: PURPOSE:To enable the use even in a section inferior in propagation condition for a space diversity receiver which is provided to a master station in a time division multi-direction communication network, by monitoring the error factor of a demodulated signal independently in response to each slave station to perform the switch selection control. CONSTITUTION:A master station 100 contains conflict counting circuits 4 in numbers equal to slave sations A, B-H which require diversity. For instance, the burst receiving signal supplied from the sation A is received through a main antenna MA and a secondary antenna SA of the station 100 and demodulated by each receiver 2. The error pulses EP given from receivers 2 are counted by the circuit 4 for station A for the burst time during which the signals are received from the station A. The circuit 4 performs a control so that a signal switch 3 selects the receiving signal side having a better code error factor. When the burst time of the station A elapses, the circuit 4 holds its state and then restarts its function at the burst time of the station A after opening gates 5 and 6. The same operation is carried out also with other slave stations B-H.
